Investing Behavioural Bias - Overconfidence

Dr Kahneman was asked what fools us most frequently. That was simple, he said: overconfidence

"It's the idea that you know better than the market, which is a very strange idea," Dr Kahneman told The Washington Post.  "Individual investors have no business at all thinking they can do better."

So beware of low liquidity stocks and there are reasons for being unloved by the market unless you think Dr Kahneman is talking rubbish.
